Andrew Wyatt, a Cosby spokesman, raises his fist as Cosby exits a courthouse in Norristown, Pennsylvania, in June 2017. Cosby was facing three counts of aggravated indecent assault from a 2004 case involving Andrea Constand, an employee at his alma mater, Temple University. But it ended in a mistrial after a jury was unable to come to a unanimous decision. Constand was the first of more than 50 women who have accused Cosby of sexual misconduct. Cosby has denied wrongdoing.

(CNN)A judge has ruled that prosecutors will be able to use Bill Cosby's 11-year-old deposition -- in which he admitted to extramarital affairs and giving some women drugs in order to have sex with them -- in his upcoming criminal trial in 2017.

The deposition is from a civil case brought by Andrea Constand, who says Cosby drugged her and then sexually assaulted her. Cosby now faces criminal charges in the case.

Cosby attorneys said he only answered deposition questions because Bruce Castor, the district attorney at the time, promised to never bring a criminal case based on Constand's allegations. Constand was a former employee at Cosby's alma mater, Temple University.

Castor said he made that promise so the entertainer would not be able to use the Fifth Amendment to avoid answering questions in a deposition, according to an email from Castor to his successor, Risa Vetri Ferman. The civil suit was the best chance Constand had for finding justice, the Castor email said.

The current district attorney, Kevin Steele, responded in court documents that a formal nonprosecution agreement never existed, just a press release. He also said this kind of immunity can only be extended to a witness, not a defendant.

In issuing the order, Judge Steven O'Neill said a promise to not prosecute Cosby in the future did not exist based upon the evidence presented in court.

This is the first time Cosby has faced criminal prosecution. He is charged with three counts of felony aggravated indecent assault from a 2004 case involving Constand.

She said she went to his home in a Philadelphia suburb for a career consultation and he gave her a mix of pills and wine that left her incapacitated and unable to consent to sex.

In January 2004, Andrea Constand, then a 31-year-old staffer for the women's basketball team at Temple University -- Cosby's alma mater -- was at the comedian's Cheltenham, Pennsylvania, home when Cosby provided her medication that made her dizzy, she alleged the next year. She later woke up to find her bra undone and her clothes in disarray, she further alleged to police in her home province of Ontario, Canada, in January 2005. She was the first person to publicly allege sexual assault by Cosby. The comedian settled a civil suit with Constand that alleged 13 Jane Does had similar stories of sexual abuse. On December 30, 2015, Cosby was charged with sexual assault in relation to the 2004 accusation, Costand's attorney Dolores Troiani confirmed to CNN. That ended in a mistrial after the jury deadlocked in June 2017, but prosecutors immediately announced they would retry the case.

Linda Joy Traitz said Cosby offered her a ride home while she was working as a waitress at a restaurant in Los Angeles that he co-owned in 1969. On the way, they detoured to the beach. They parked and he offered her drugs "to relax," she alleged. After refusing "he kept offering me the pills," she alleged, and it made her feel uncomfortable. She claimed he then groped her chest, pushing her down in the seat and toward the door, and tried to lie on top of her. She got out of the car and ran, she said. She added that she was "absolutely not" raped. He tried to calm her, she said, then drove her home in silence. Traitz has a criminal record in Florida and spent time in prison on a conviction for drug trafficking, according to state records. Cosby's lawyer passed on her lengthy rap sheet.
